Coffea Arabica Losing Leaves
Hi I'm new to this forum and I have just gotten my first plants! I'm excited to get going, but it seems like I'm hitting some issues.
One of them is a coffea arabica plant that's in a 12" pot and is about 4 feet tall. Since I got it about 2-3 weeks ago, I've been noticing the leaves are falling at a pace that seems to be quicker than normal (and speeding up). I think I picked up 10-12 leaves in the last 2-3 days. I attached a picture of the leaves with the stem at the top of the picture and the tips at the bottom. Some have brown tips, but are still pretty green. Others are browning all throughout and then falling off. Some of the leaves that have fallen seem to be pretty green otherwise. These leaves seem to be mostly at the mid-level and lower parts of the tree. The leaves in the picture are just some of the ones that are falling. I know moving it to my house from the nursery will aggravate the tree a little.
I have it in the corner of my condo (inside) next to a sliding glass door. It was getting a few hours of direct sun light, but since then I have pulled up my honeycomb shades to block the direct light (See the picture). I've been feeding it tepid tap water, but the woman at armstrong told me to get it some bottle water instead since Los Angeles tap water is not very good. She also gave me some liquid Miracle-Gro fertilizer to add to the bottled water I give to the plant. However, I'm a little afraid of shocking the plant some more with inducing fertilizer. I just started to spray the plant yesterday in hopes that may help with humidity. Is it too close to the window making it too cold? Temps out here have been 30s F and 70s F, but the inside of my condo has probably been high 50s (at worst is my guess).
Any ideas? Use the liquid fertilizer, bottled water, and move it away from the sliding door? Any help would be appreciated. Thanks!
